The table which represents a linear function is:
x y
1 5
2 10
3 15
4 20
5 25
The table of x and y values represent a linear function if for each equal increase in the x-value there is an equal increase/decrease in the y-value.
The table of values is:
In this table the x-value is increasing by a constant value 1.
( since,
2-1=1
3-2=1
4-3=1
5-4=1 )
and the y-value is also increasing by a constant value 5.
10-5=5
15-10=5
20-15=5
and 25-20=5 )
Answer:
(+6) + (-11) + (+5)+(-7)
(6) + (-11) + (5) - (7)
6 - 11 + 5 - 7
(6 + 5) + (-11 - 7)
11 - 18
= -7
